Laminar Research released X-Plane version 6.0.5b2. The new version completely changes the outside world by remodelling the Earth to be truly round. This has a number of positive implications in the game, thus allowing the user to circumnavigate the Earth realistically, and it reduces terrain "jiggling."

Additionally, a few minor realism enhancements have been added and some bugs have been fixed. The load time has been improved as well.

X-Plane is a realistic general-aviation flight simulator with extensive modularity, allowing players to design their own aircraft, systems, and terrain. X-Plane comes bundled with a number of predesigned aircraft, helicopters, and spacecraft, and is the only flight sim for Macintosh that models Mars as well as Earth.
